Low users of SNS seemed to exhibit lower body image dissatisfaction than average to extremely high SNS users. Females exhibited higher body image dissatisfaction than males (p<0.05), consistent with previous findings. There was a significant association between BMI and body image dissatisfaction (p<0.05).
